History: 
Not every hero is equipped to deal with the threat of magic, so when the Justice League is beaten by an out-of-control Enchantress, help arrives in the form of a decidedly strange team of supernatural adventurers. Led by the infamous John Constantine, the group decides it must stay together to confront serious threats that are looming on the horizon. Of course, as with all situations involving Constantine, nothing is what it seems, and soon the team is involved in a web of tangled plots involving mystical artifacts, the all-powerful Books of Magic and even Steve Trevor and ARGUS. Wielding magic always comes with a cost…and fighting magic surely means even more is at stake.
